CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of U. S. Provisional Patent Application No. 60/961,613, filed Jul. 23, 2007, the entire disclosure of which is incorporated herein in its entirety.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention pertains to structured panels for dividing a room or space. More particularly, the present invention relates to a room divider panel that extends between the floor and the ceiling and extends/retracts between opposite walls of a hospital room or medical private area to temporarily divide the room/area into separated and private spaces. Even more particularly, this invention relates to a space divider panel structured to include an inner layer of sound-deadening material to inhibit sound from passing between the separated spaces. Even more particularly this invention relates to a space divider assembly that includes an extender/retractor arrangement and wipers impregnated with an antibacterial and/or antimicrobial substance that engage and sanitize opposite faces of the divider panel upon extension/retraction thereof.

2. Prior Art

The use of a panel or divider to separate and divide a room or area into two or more areas is known to those skilled in the art to which the present invention pertains. Typically the divider forms a continuous wall or barrier. The divider may be much like a shower curtain wherein a sheet of polymeric material is suspended from a rod and the curtain moves from a stored position, wherein the curtain is bunched up and the shower area is open, and an extended position wherein the shower area is closed. In other arrangements, the divider may be in the form of a series of articulated panels, which are suspended from an elongated track, and move from a stored position, wherein the panels are folded and/or collapsed upon one another and the area is open, and an extended position, wherein the panels unfold and form a continuous wall closure.

Arrangements using partitions, curtains, dividers and the like are used in patient areas of hospitals. Generally, these dividers are temporary, and much in the nature of the shower curtain arrangement hereinabove described. That is, rings and the like atop a top edge of a sheet of cloth-like material hang the curtain for horizontal sliding movement relative to a support rod.

However, while suitable for providing some minimal degree of privacy, large vertical gaps are formed between the top and bottom edges of the curtain and the floor and the ceiling. These gaps permit light to pass between the divided patient spaces. Additionally, noises from one side arising from the voices of medical staff, a patient and visitors of the patient as well as noises arising from medical procedures pass relatively unimpeded to the other side of the divided room. Conversations between the medical staff and the patient are not private. Loud and boisterous visitors can irritate or impede the recovery of some patients.

Additionally, while room dividers are capable of being cleaned, the divider is typically cleaned only when there is a need, such as when something that is spilled thereon is visible to the eye. In a hospital, and in particular in patient areas, the regular cleaning of a room divider is important to inhibit the growth of mold or the exposure of a patient to bacteria and germs arising from ongoing checking in and out of patients or exposure to visitors.

An object of this invention is the provision of a room dividing arrangement, particularly for use in a patient area subject to germs and the spread of bacteria, which arrangement includes a structured room divider panel and support system therefore that is easy to use in a manner that the divider panel easily extends/retracts relative to the support system and forms a closure between spaced walls and the floor and the ceiling when extended from one wall, the support system enabling the divider panel to be self cleaning upon use to aid in protecting a patient in one part of the room from exposure to germs, bacteria and the like from another patient or visitors entering the other part of the room and the panel having acoustic sound deadening properties to provide privacy and a quieter recovery environment to patients in different parts of the room.

SUMMARY OF THE INVENTION

The present invention is directed to an improved room divider arrangement for dividing a room having a floor and ceiling and spaced walls into at least two separate areas, the divider arrangement employing

-   -   a housing connected to one said wall, said housing extending         between the floor and the ceiling and including an interior         chamber and an inlet communicating with the chamber,     -   a winding mechanism in said chamber, said mechanism including a         roller disposed for rotation in first and second directions         relative to a vertical axis between the floor and the ceiling,         means for locking and unlocking the roller for rotation, and         means for pulling the roller in said second direction,     -   an extensible/retractable panel of flexible material, said panel         having laterally spaced first and second ends and vertically         spaced upper end lower edges and sized to extend between the         walls and between the floor and ceiling and form a closure         therewith, the panel being wound relative to said roller with         the first end thereof fixed to said roller, wherein when the         roller rotates relative to said chamber and in said first and         second directions, respectively, the second end thereof unwinds         from the roller and extends outwardly in said second direction         to an unwound position and retracts inwardly towards and into a         wound position about the roller, and     -   means for mounting and constraining the upper and lower edges of         the panel for movement between the wound and unwound positions.

Preferably, the divider arrangement provides cleaning structure for automatically cleaning the opposite sides of the panel upon extension and retraction, the cleaning structure including a pair of elongated antibacterial applicators of resilient material disposed in the inlet to the interior chamber and in close juxtaposed relation with one another, the applicators being provided with an antibacterial and/or antimicrobial substance and adapted to wipingly engage the opposite sides of the panel to sanitize the panel sides as the panel is either extended or retracted.

Preferably, the divider panel is structured to include an inner layer of sound deadening or muffling material sandwiched between two outer layers, the layers being thin, flat, coextensive with one another, and sufficiently flexible to wind or coil about the roller. The outer layers are squeezed and wiped clean by the antibacterial applicators during extending/retracting movement of the panel relative to the chamber.

Preferably, the outer layers are comprised of a suitable vinyl, in part because vinyl doesn't give off offensive odors, which are especially noticeable as the temperature increases, are light in weight yet offers equal or superior damping ability, and bends and stretches without cracking or recoiling, and applies without a heat-gun. Formulations may include a flame retardant.

The inner layer of sound deadening material may be comprised of other materials, such as bitumen or asphalt, a fibrous material or loosely woven fiberglass, natural or synthetic rubber, PVC, chlorinated polyethylene or ethylene vinyl acetate copolymer, and fillers.

A sound deadening material according to the present invention is preferably adapted to provide an acoustic barrier to sound transmission between 125 and 4,000 Hz.

The outer layers each comprise a strong sheet of vinyl, resistant to attack and degradation by antibacterial and/or antimicrobial cleaning solution. The inner layer is sandwiched between and intersecured to the outer layers, such as by gluing, and in a manner wherein the layers are generally in parallel relation with one another when intersecured. The intersecured panel layers provide an airtight seal about their conjoined outer peripheries, aiding in the deadening or muffling of sound transmission.

The means for mounting and constraining a first means for joining the upper edge of the panel for movement between the wound and unwound positions, and comprises an elongated guide track, the track extending across the ceiling and from the housing connected to the one wall and to the other wall. The upper edge of the divider panel is supported by, suspended from, and constrained for movement in the upper guide track.

The means for mounting and constraining also includes a second means for joining the lower edge of the panel for movement between the wound and unwound positions, and comprises an upwardly open lower guide track that is affixed atop the floor and a guide pin. The guide pin includes an enlarged rubber grommet that extends downwardly from the lower panel edge and into opening of the guide track, wherein to constrain the panel movement and ensures that the panel is vertically disposed between the floor and the ceiling.

In an aspect, a longitudinally extending sealing skirt operates between respective of the upper panel edge and the guide track to form a “dynamic” acoustic barrier or seal-like closure to seal between any possible vertical air gap that may exist along the top longitudinal edge of the panel.

Similarly, the lower panel edge is disposed within the opening of the lower guide track and the interfitment therebetween forms, at least in part, an acoustic barrier therebetween.

The means for locking and preventing/permitting rotation of the roller may comprise a spring biased ratchet mechanism.

Depending on the application, an electrical motor may be operably connected to the roller to rotate the roller, and thereby retract and wind the divider panel into coiled extensible relation about the roller.

The room divider arrangement includes a vertically disposed pull housing at the extensible end of the divider panel or partition, a lock mechanism in the pull housing, and a first and second lock housing.

The lock mechanism includes an upper and lower lock pin, an actuatable lock handle operable to move the locks pins from a first (extended) position to a second (retracted) position, and means for biasing the lock pins into the first position. In a preferred embodiment, the upper lock pin is captivated in a recess of the upper lock housing, the lower lock pin is in the recess proximate to the floor, and the pins move when the handle is actuated.

The first lock housing is fixedly disposed in the upper guide track and the second lock housing is proximate to the lower edge and comprises a rubber stop adapted to engage the floor and provide flexibility in maintaining the position of the panel when less than complete extension/retraction of the panel is desired.

The handle/spring normally biases the stopper into engagement with the floor to resist unwanted extending/retracting movement of the panel when the handle is in the first position.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

In a preferred embodiment of the present invention, and referring to FIGS. 1 and 2, there is provided a room divider arrangement, generally indicated by the reference number 10, for dividing a room 12 into two separate areas 12A and 12B. The room 12 includes a floor 14 and ceiling 16, a first pair of vertical walls 18 and 20, and a second pair of vertical walls 22 and 24.

The room 12 is representative of that found in a patient area of a hospital and includes two patient beds 26 and associated facilities (not shown) to provide medical services to patients in the beds.

According to this invention, the room divider arrangement 10 includes a pair of elongated guide tracks 28 and 30, a storage housing or enclosure 32, and a closure or room divider panel 34. The guide tracks 28 and 32 extend between the walls 18 and 20 and operate, in part, to mount and constrain the panel 34 for horizontal extending movement away from and retracting movement towards and into the storage housing 32. While shown as being straight, the tracks may form a curve. Importantly, the tracks are positioned in a manner to maintain the panel 32 in a vertical plane “V” (i.e., in perpendicular relation with the floor 14 and ceiling 16).

As shown in FIG. 4, the lower guide track 28 is formed by a pair of strips or bands 15 of elastomeric material, each affixed to the floor 14 in side-by-side relation to define an upwardly open groove 17 that is adapted to connectingly receive the lower edge 34 a of the divider panel 34. Advantageously, these strips may be easily affixed and removed from the floor, when desired.

While shown as being generally flat and of rectangular cross-section, the upper surfaces of the strips 15 may be angled upwardly to limit the likelihood of tripping.

Further, the guide track may be an upwardly open channel having a squared-C cross-section, mounted atop the floor or disposed in flush-mounted relation with the floor surface.

As shown in FIG. 3, the upper guide track 30 is affixed to the ceiling 16, of squared-C cross-section, and downwardly open. The guide track 30 is adapted to receive roller wheels connectingly mounted to the upper edge 34 b of the divider panel 34.

The housing or enclosure 32 is connected to the wall 18 and extends vertically between the floor 14 and the ceiling 16 and terminates proximate to respective ends of the lower and upper guide tracks 28 and 30. The housing 32 forms an encasement and includes an interior chamber 31 for mounting the panel, at least in part, and a vertically disposed inlet or passage 36 that communicates with the chamber 31.

As shown in FIG. 5, a pair of elongated antibacterial applicators 38 are juxtaposed with the inlet 36. Preferably, the applicators 38 are mounted in the inlet 36 and disposed in closing relation to the chamber into and from which the panel 34 is extended/retracted.

The applicators 38 are of a resiliently compressible, such as comprised of a sponge-like material, and impregnated with an antibacterial and/or antimicrobial substance to kill germs and fungi such as mildew. The applicators 38 have respective end faces 38 a positioned for wiping and sanitizing engagement with and against the opposite sides of the panel 34 as the panel is either extended or retracted through the inlet 36.

A winding mechanism for supporting the room divider panel 34, at least in part, is disposed in the chamber. While not shown as understood by one skilled in the art, the winding mechanism is much like that found in a conventional window shade and includes a winding roller disposed for winding/unwinding rotation in first and second directions relative to a vertical axis between the floor and the ceiling, ratchet structure for locking and unlocking the winding roller for winding/unwinding rotation, and a spring for driving (i.e., biasing) the winding roller for rotation in the second direction wherein to retract (i.e., rewind the panel about the winding roller).

Depending on the application, an electrical drive motor may be employed to drive (i.e., rotate) the winding roller in the retracting/rewinding second direction and into coiled extensible relation about the winding roller.

The room divider panel 34 is generally rectangular and sized to extend between the walls 18 and 20 and between the floor 28 and ceiling 30 whereby to form a closure therewith, when extended. The panel 34 comprises a single continuous thin one-piece extensible/retractable structured sheet of flexible material having horizontally spaced first and second end portions 34 c and 34 d, proximate the walls 18 and 20, when the panel is extended, and vertically spaced lower and upper edges 34 a and 34 b, proximate to the guide tracks 28 and 30, when the panel is extended.

The first end portion 34 c of the divider panel 34 is fixedly connected to the roller and the divider panel is wound (i.e., coiled) about or unwound from the winding roller, depending on the direction of rotation of the roller. When the roller rotates relative to the chamber and in the first and second directions, the second end portion 34 d of the panel 34 unwinds (i.e., is uncoiled) from the roller and extends horizontally away from the roller, or retracts horizontally towards and is wound (i.e., coiled) about the roller.

The divider panel 34 is structured to include an inner layer 40 of sound deadening or muffling material sandwiched between two outer layers 42, the layers 40 and 42 being thin, flat, coextensive with one another, and sufficiently flexible to wind or coil about the roller.

Preferably, the layers 40 and 42 are comprised of a suitable vinyl, in part because vinyl doesn't give off offensive odors, which are especially noticeable as the temperature increases, are light in weight yet offers damping ability, and bends and stretches without cracking or recoiling, and applies without a heat-gun. Formulations may include a flame retardant.

Preferably, each outer layer or sheet 42 is comprised of a strong sheet of vinyl, such as a vinyl lining material or a vinyl coated fabric, which is resistant to attack and degradation by antibacterial and/or antimicrobial cleaning solution arising from application of antibacterial cleaning materials commonly found in hospitals to eliminate mold, kill germs, and otherwise prevent the spread of germs as well as be resistant to attack from moisture. The outer layers 42 must be of a suitable thickness to be strong yet withstand the constant squeezing engagement and exposure to the wiping edges 38 a of the antibacterial applicators 38 during extending/retracting movement of the panel 34 relative to the inlet 36 leading into the housing chamber.

The outer layers 42 may also be comprised of a strong durable sheet of a flexible polyethylene, polystyrene, or acrylic or other suitable synthetic flexible sheet material.

Preferably, the inner layer 40 is comprised of a sound deadening vinyl.

In addition, depending on the application, the sound deadening material of the inner layer 40 may be comprised of bitumen or asphalt, a fibrous material or loosely woven fiberglass, natural or synthetic rubber, PVC, chlorinated polyethylene or ethylene vinyl acetate copolymer, and fillers.

Preferably, a sound deadening material according to the present invention is adapted to provide an acoustic barrier to sound transmission between 125 and 4,000 Hz.

The inner layer 40 is intersecured or laminated to the outer layers 42, such as by a process that employs adhesive gluing and/or fusion bonding and is resistant to delamination, and the layers are generally parallel relation with one another when intersecured. The intersecured panel layers 40 and 42 provide an airtight seal therebetween and about their conjoined outer peripheries, aiding in the deadening or muffling of sound transmission as well as vibration damping.

A plurality of laterally spaced roller assemblies 44 connect and mount the upper edge 34 b of the room panel 34 to the guide track 30 and suspend the panel from the ceiling 16. As shown in FIG. 3, the roller assembly 44 includes a pair of rollers 46 which are journalled for rotation on a common shaft 48, and a bracket 50 extends through a central opening 31 of the guide track 30 for mounting the shaft 48 and the rollers 46 to the edge portion 34 b of the divider panel 34 and for rolling movement within the confines of the track 30.

In some applications, a longitudinally extending sealing skirt 52, preferably of sound deadening or muffling material, operates between each respective side of the panel edge 34 a and 34 b and the guide track 30 to form an acoustic seal between any vertical gap that may exist between the upper edge 34 a of the panel 34 and the track 30.

As shown in FIG. 4 and as discussed hereinabove, the lower guide track 28 is formed by a pair of side-by-side strips or bands 15 of elastomeric material and an upwardly open groove 17. The lower edge 34 a of the divider panel 34 is interfitted within the groove 17 in a manner that little or no gap is formed, thereby completing, at least in part, an acoustic seal.

Preferably, at least one guide pin or grommet 35 extends from the lower edge 34 a and into the groove 17 to constrain the panel 34 to move along a path complementary to the upper guide track and maintain the suspended panel in a vertical plane “V”.

Referring to FIGS. 2 and 6, the room divider arrangement 10 further includes a vertically disposed pull housing 54 at the extensible end 34 d of the divider panel or partition 34, and a lock arrangement for securing the panel 34 in room separating relation. The lock arrangement includes an upper and lower lock housing 56 and 58 and a lock mechanism 60. The lock mechanism 60 is operably associated with the pull housing 54 and includes upper and lower lock pins 62 and 64, an actuatable lock handle 66 for retracting the pins from a first position to a second position, and a torsion spring (not shown) acting to bias the handle and the lock pins into the first position.

The upper lock housing 56 is fixedly secured interiorly of the upper guide track 30 and includes a recess 56 a adapted to captivate the lock pin 62.

The pull housing 54 is used to pull the forward end 34 d of the panel 34 away from the wall 18 and towards the wall 20 and register the lock pin 62 with the lock housing 56.

The lower lock housing 58 is in the form of a sphere, comprised of rubber or like elastomer, and is fitted to the end of the lower lock pin 64, is positionable in the recess 17 formed between the strips 15, and is normally biased into contact with the floor 14. The sphere or lock housing 58 forms a stopper that normally engages the floor 14 to inhibit unwanted retraction of the panel and position the panel in a less than complete room separating relation.

In operation, substantially simultaneously, the handle 62 is rotated, whereupon the lock pin 62 and 64 are retracted from the first position and associated relation with the lock housings 28 and 30, and the pull handle 60 pulls the panel edge 34 d to the wall 20 and the locking pins into the second position. The panel and locking pins may be moved to a position between the walls 18 and 20, the handle released, whereupon the locking pin 64 will drive the stopper downwardly and into frictional engagement with the floor. The panel may be moved proximate to the wall 20 whereupon the lock pin 60 is registered with the lock housing 56, registered with a captivating recess 56 a of the lock housing 56, the handle released, and the pin 62 biased into locked (i.e., nested relation) with the recess 56 a, and preventing the panel from being drawn backwards towards the wall 18. While suitable arrangement are known by those skilled in the art, a torsion spring (not shown) is preferably used to bias the pins towards their respective guide tracks 28 and 30.
